Bohler A7 FD description: The weld deposit offers high ductility and elongation together with excellent crack resistance even when subjected to thermal shock. It will work harden and offers good resistance against cavitation. Ductility is good even after high dilution when welding problem steels. Beside the major savings in time and cost BÖHLER offers a high production quality level together with lowest probabilities for welding errors. Increased travel speeds as well as little demand for cleaning and pickling provide considerable savings in time and money.
